Question

我正在关注序列化大文件块的示例here。不管怎么说是序列化的新手，我现在已经丢失了传递给我的Serialize方法的参数。由于OOM异常，我搁置了我使用yesterday的方法。非常感谢您的帮助。

Public Shared Sub ReadAndProcessLargeFile(theFilename As String, ByVal obj As LocalDBObject, Optional whereToStartReading As Long = 0)
Dim bf As New BinaryFormatter() ' Create a binary formatter for this stream.

Using fileStram As New FileStream(theFilename, FileMode.Open, FileAccess.Read)
    Dim buffer As Byte() = New Byte(fileStram.Length - 1) {}
    fileStram.Seek(whereToStartReading, SeekOrigin.Begin)
    Dim bytesRead As Integer = fileStram.Read(buffer, 0, buffer.Length)
    While bytesRead > 0
        bytesRead = fileStram.Read(buffer, 0, buffer.Length - 1)
        'It is here where I am now lost. What parameters do I supply to my Serialize method below 
        bf.Serialize()
    End While
End Using
End Sub

嗯，该代码只是没有序列化任何东西，序列化你应该这样做：

Public Shared Sub Serialize(theFilename As String, ByVal obj As LocalDBObject)
    Dim bf As New BinaryFormatter() ' Create a binary formatter for this stream.

    Using fileStram As File.Create(theFilename)
        bf.Serialize(fileStram, obj);
    End Using
End Sub

但我怀疑这不是你想要的，除非你解释得更好，你的问题很难理解你想要达到的目标。
